CNN Exclusive: Tracking a Cyber Criminal

CNN’s Drew Griffin reports on Ukraine’s Maksym Yastremsky, who has stolen over 40 million cards from mostly U.S.-based retailers and who cost credit card companies over $11 million. Up until the most recent Target Store breach, Yastremsky was the most prolific credit card hacker in the world who organized and operated a worldwide credit theft ring that hacked into nine major retailers.

In a CNN exclusive interview, Griffin talked with the secret service agent who was posing as a new partner in the criminal ring. Ultimately, the agent helped to nab the cyber criminals at the heart of this hacking underworld.
